Method of processing non-real time service and broadcast receiver

Abstract

A method of processing a non-real time service of a broadcast receiver, which receives and processes a service being transmitted in non-real time, and a broadcast receiver are disclosed. Herein, the method of processing a non-real time service of a broadcast receiver includes receiving a signaling information table including additional information on contents configuring a non-real time service and a content identifier for each content, acquiring the additional information on contents and the content identifier for each content from the signaling information table, storing contents being downloaded through a FLUTE or an internet in a storage medium, based upon the additional information on contents and the content identifier for each content, and displaying a list of recordings including the contents stored in the storage medium, wherein a list of recordings screen displaying the list of recordings includes at least one of a content name, a channel name, a date of recording, and a content size.

What is claimed is: 
     
       1. A method of transmitting a broadcast signal for a broadcast service, the method comprising:
 generating the broadcast signal having the broadcast service, and signaling data for signaling the broadcast service, wherein the broadcast service includes one or more non-real time contents, each of which consists of one or more files, 
 wherein the signaling data includes a content information element containing information describing the one or more non-real time contents available for download to storage in a broadcast receiving device, 
 wherein the content information element includes content linkage information used to link the one or more files described in a file description element which contains metadata for the one or more files belonging to a non-real time content of the one or more non-real time contents; and 
 transmitting the broadcast signal and the signaling data, 
 wherein the content information element further includes content size information representing size of the non-real time content, wherein the content size information is used by the broadcast receiving device to determine if enough memory is available to store the non-real time content before downloading is attempted, and 
 wherein the content information element further includes update availability information specifying whether updates are expected for the non-real time content or not. 
 
     
     
       2. The method of  claim 1 ,
 wherein the broadcast signal further includes service information element containing information for service acquisition for broadcast services, and 
 wherein the service information element includes service category information specifying a category of the broadcast service that corresponds to a non-real time service. 
 
     
     
       3. The method of  claim 2 ,
 wherein the service information element is carried in IP (Internet Protocol) packets with a specific IP address and a specific port number. 
 
     
     
       4. An apparatus for transmitting a broadcast signal for a broadcast service, the apparatus comprising:
 a broadcast signal generator that generates the broadcast signal having the broadcast service, and signaling data for signaling the broadcast service, wherein the broadcast service includes one or more non-real time contents, each of which consists of one or more data files, 
 wherein the signaling data includes a content information element containing information describing the one or more non-real time contents available for download to storage in a broadcast receiving device, 
 wherein the content information element includes content linkage information used to link the one or more files described in a file description element which contains metadata for the one or more files belonging to a non-real time content of the one or more non-real time contents; and 
 a transmitter that transmits the broadcast signal and the signaling data, 
 wherein the content information element further includes content size information representing size of the non-real time content, wherein the content size information is used by the broadcast receiving device to determine if enough memory is available to store the non-real time content before downloading is attempted, and 
 wherein the content information element further includes update availability information specifying whether updates are expected for the non-real time content or not. 
 
     
     
       5. The apparatus of  claim 4 ,
 wherein the broadcast signal further includes service information element containing information for service acquisition for broadcast services, and 
 wherein the service information element includes service category information specifying a category of the broadcast service that corresponds to a non-real time service. 
 
     
     
       6. The apparatus of  claim 5 ,
 wherein the service information element is carried in IP (Internet Protocol) packets with a specific IP address and a specific port number.
